摘　　要：本文介绍了甲醛银催化法生产的工艺流程和生产特点。基于三环节能量流结构模型,对某甲醛装置进行了各个环节的能量平衡分析和火用分析,找出过程用能的薄弱环节,并提出了相应的改进措施。减少配料蒸汽的加入和合理利用反应热多副产蒸汽是用能改进的主要方向。The primary technologies and characteristics of formaldehyde synthesis using silver as catalyst were introduced. Based on the three-link energy structural model, the energy analysis and exergy analysis were conducted for a formaldehyde synthesis process. The optimization directions and corresponding improving measures were proposed, which including the decrease of feed-steam and the reasonable utilization of reaction heat to generate more steam, etc.
